METALLIOFRAME. CONSTRUCTION.

Application filed November 16, 1927. Serial No. 233,681.

This invention relates to metallic frame construction, and particularly to improvements in the means of attaching sheathing and the like to the frame work.

The object of the invention is to provide a simple etlicientand economical fastener whereby the material forming the wall structure rapidly and securely attached to framework of metal.

A further object is to provide a fastener aoapted to secure wall material of any thickness to metallic framework.

A further object is to provide a fastener that made integral with the metallic Framework but of a more flexible material and one adapted to bend readily and to be clinched on the outer surface of the material to secured to the framework.

.1 am aware that studding with turned out prongs has been employed in frame construction, but .in order to form the prong and bend it outwards, the studding had necesss 'ily to be. made of sheet metal which was of thin bendable material.

When thicker and more rigid studding was employed. it was found to be impossible to provide bent prongs that were suitable for clinching on the applied sheathing. Prongs pimched in and turned out in heavy studding could not be made with suitable points or with a sutliciently narrow stem to permit th ir. to penetrate through wall board and iiick sheathing.

The use of studding in the form of angles,

channeis, Z bars and other standard shapes.

when made of thicker and heavier metal the sheet metalv provided a much stronger f amework and by means of my invention the application of sheathing and the like of any thickness is readily accomplished in a Yery-secure manner.

Reference is made to the accompanying d rawings in which Figure 1 is a cross section of an angle bar showing the manner the fasteners are mounted.

Figure 2 is a cross section of another form of bar mounted with fasteners.

Figure 3 is a cross section of an angle bar showing how the fasteners are clinched on the applied sheathing.

Figure 4 shows how wires and the like are secured.

Figure 5 shows how the fastener is employed with thick layers of sheathing.

In Figure 1. a section of an angle bar 1, shown with pins 2, projecting from the outer faces. The pins 2, are in the form of short rivets secured in holes 10, bored in the angle bars 1, and having extensions with points 21, of suitable length for the thick ness of the material to be attached.

These pins 2, are made of material firm enough to readily penetrate sheathing such as wall board 3, when it is driven against them, and flexible enough to have the protruding points 21, readily clinched.

Thus in Figure 3, wall board 3, is shown on the upper face of the angle bar 1, while on the side face, paper 4, wire 5, and expanded metal or wire mesh 6, all held. in position by the clinched ends of the pins 2.

Figure 1, shows the manner of mounting wires 5, on the pins 2, over paper 4, Figure 5, shows how a thick sheathing 7, can be $6- cured to bars 1.

WVith a frame of bars furnished with such projecting pins the application of sheathing and the like is quickly, easily and securely carried out by unskilled labour and the construction of partitions and walls of this type becomes very simple operation.

The pins 2. can be mounted in studding of a variety of forms such as U bars, channels, I bars, without difliculty and at any required interval.

The barsso mounted can be made in quantity to specification, and great economy in time and labour thereby secured in applying the. sheathing to the bars and securing it firmly in position. i

I claim:

In metallic framework construction the combination of a studding of rolled stock, a series of holes bored therethrough, with a series of pointed bendable spikes secured in the holes, adapted to penetrate sheathingand the like and to retain the same by having the spike ends clinched thereon.
